ROLLER-BEARING.

Specification of Letters Patent.

Patented June 9, 1908.

Application filed August 8, 1907. Serial No. 387,612.

" reference being hadto the annexed drawing,

- tached. Fig. 4 is a detached -view making a part of this specification, and to thereon, in which- Figure 1 is a side elevation. vof the roller bearing rings showing the rollers in proper relative position; Fig. 2 is an end view showing the different parts placed in proper position, also showing the cone. Fig. 3 is a sectional view showmg modified cups atof one of the outer cage rings. Fig. 5 is a detached view bf the center vcage ring". lFig. 6 is a detached view of the cone. Fig. 7 is a detached view of one of the rollers. Fig'B is a sectional view showing all of the different parts properly assembled and the axle in position.

The present invention has-relation to roller bearin s, and it consists in the novel arrangenient escribed and particularly pointed out in the claims. y

Similar numerals of reference indicate core responding parts in all the figures of the drawing.

ln the accompanying drawing, 1 represents one of the cone-sleeves, which conesleeves are located upon the axle 2 substantially as shown in Fig. 8. rlhe relatively fixed roller-bearing cup members 3 and 4 are telescoped together and are each provided with the enlarged cup portions 5 and 6, which cup portions are provided with beveled inner surfaces 8 and 7. The cups 5 and 6 are piovided with the screw threaded extensions 9 and 10 into which screw threaded extensions are entered the relatively adjustable bearing cups or collars 11 and 12, which cups or collars are provided with the beveled peripheries 14 and 13, said beveled peripheries corresponding in angularity with the beveled inner peripheries of the cups 54 and 6, and for the purpose hereinafter described, the cups or collars 11 and 12 are adjustably attached by screw threads to the cups 5 and 6. The bearing rollers 15 are journaled at their ends to the cage rings 16 and 17, which' cage rings are held in proper spaced relationship with reference 4to each other by the numerals and gures of reference marked tact.

means of the tie rivets 18. lIn assembling the bearing rollers the center cage ring 17 and one of the outer cage rings 16 together with one set of the rollers 15 are properly connected together, after which the cone- .sleeves 1 are placed in proper position and the reinainimr outer cage ring and the. reinaining set o rollers are properly connected by the rivets 18.

lt will be understood that after the rollers 'and the cage rings have been properly connected the cone shaped sleeve l could not be inserted, owing to the fact that the cone sleeve is of greater diameter at `its center or mid-way between its ends than the outer cage ring 16.

It will be understood that the cups 5 and 6 are to be placed in the hub of a vehicle Wheel in the usual manner, but this feature does not have any-reference to thepresent invention.

For-thepurpose. of locking the cup-mein bers l1 and l2 in. proper adjustment, the rings `19 are provided, which rings are located each upon the screw threaded peripheries of the cups or collars 11 and 12. The outer cup or collar 12 is closed at its outer end and is so formed for the purpose of providing a dust cap. The bearing rollers 15 are slightly tapered and are so tapered for the urpose of properly fitting the periphery oft e cone sleeve land the inner beveled surfaces of the outer and inner cu s. The rollers 15 are inclined in opposite directions from the center cage ring 17 and are so inclined for the pur ose of taking the end thrust of the axle 2. it will be understood that there is some end movement of the axle-2, and by providing the opvositely inclined bearings they will receive t e thrust in both directions. By adjustably connecting the cups or collars 11 and 12 tothe cups 5 and 6 I ain enabled to take up the wear from time to time,` thereby roviding a means forv roperly adjusting tlie rollers to the di' erent parts, with which said rollers come in con By providing the center cage ring 17 is a space between the inner ends of the oppositely` inclined bearing rollersv 15 at w ich point the surface of the cone-sleeve will not receive any Wear'and in Aorder to pre- .vent ythe formation oa ridge upon the center portion of the cone shaped sleeve 1, said center portion is rovided with the annular there groove 20, whici annular 'groove is located directly beneath the center cage ring 17 Such tact witlithe ring Cir above described when the ditl'erent parts areproperly asseni- `located between the oppositely inclined peled.

Each roller cage is provided with two sets of rollers inclined in opposite directions as and for the purpose speci- '.lied, that is to say to so locate the two sets of rollers of each cage containing the rollers in osition that When the cups or collars l1 an 12 are properly adjusted the rollers 15 will be brought in proper contact with the peripheriesot' the cone-sleeves and the inne-r inclined surfaces of the cups 5 and 6 and the cups or collars 11-and 12. The'rcllers 15 being provided at theirl ends with reduced portions 1 5*l for the purpose ot being journaled in the rings 16 and 17 necessarily have shoulders upon them at the point where such rcduced portions end and the` roller proper begins. The inn-er ends ol the rollers 15 by ineaiis of their reduced portions at those ends provided, are jouriialed'in the rings 17. To prevent the shoulders upon the inner ends of said rollers 1,5 from eoining into con- 17 and providing friction at that point the reduced portions ot' .said rollers 15 -are niade otsnllicient length to enter the bearings provided for them in the ring 17, and to permit said reduced portions to' ineet`or abut end to end in pairs in said ring 17. 'lhese ends then may Arotate together within the bearings in the ring 17 and the shoulders on the rollers 15 are thus prevented from coming into direct contact with the rings 17 and preventing any end thrust of said rollers against said ring.

ln Fig. 3 l illustrate a modification which and 6a ot a consists in forming the cups 5'LL length to correspond substantially with the v axley bearings or length of the roller bearing cage, which parts are formed separate from the hub and are adjustably connected together by screw threads. All of the parts shown in Fig. 3

constitute what might be termed a sell contained structure designed to be placed in the hub ol a wheel. I`

It will be understood that the present iiivention can lit:ijiplietl to other bearings than wheel bearings as it is ol' no ini )oi-tance whet'lieith `outer member revolves or the inner nieniber or spindle revolves and hence l do not desire to be conlined' to the* specilic class olv bearings.' herein described. or inv other words Avehicle axle bearings.

. llaving l'iilly described my invention what I claim as new and desire to secure by ,liettersfPatent, isd i 1. ln a roller-bearing, cup members provided with cup sections, said cup sections provided with screw threaded extensions, cups or collars adjustably attached to the screw threaded extensions of the cup sections, cone-sleeves eacli'liaving oppositely inclined peripliei'ies. there being agroove rings, rollers journaled riplieries ol each cone sleeve, roller cages and sets of rollers journaled in the cages the rollers being inclined in opposite. directions. substantially as and loetlie. purpose specilied. v 2. In a rollerbeariiig. a. sleeve', its periph fixed bearing cups and relatively 'adjustable y bearing cups connected to the cups, roller cages consisting ol' li.\fed bearing of annular sets inclined tions arranged in endwise relation toeach other and rings adjustably connected to the relatively adjustable bearing' cups, substan tially as and l'or the purpose specilied.

"4. In a roller bearing, the combination oll oppositely inclined c-oiie-sltfeves7 relativel)v liXed bearing cups and relatively adjustable bearjng cups `connected fixe( v in .the rings, said rollers consisting ol' 'annular sets inclined i'n opposite directions arranged in 'endwiserei lation with each other, rings adjustably connected to they relatively adjustable bearing cups, and the outer bearing cup const'itiitiig a dust cap, substantially as and lor the purpose specified.

.5. In a roller bear'i. g ot the class described, a cage consistiin; of rings spaced from each other, rollers journaled intlie rings and the inner reduced ends or bearings of saidrollers abutted against Aeach other; a sleeve and bearing cups saidr rollers located between said bearing cups and sleeve, substai-itially as and l'or the purpose specilied.

(i. ln a roller bearing,
